How to gain more depth with the Xp deus

[Finder82]

I copied this text directly from the Finnish forum, it may interest you:

Translated this test to English from an Austrian forum.
Pretty remarkable to see the effect discrimination has on depth.
Thought you might be interested in the results.
The test was done according to Ingo standards.
________________________________________

Today, we were at the "borehole" on our testsite with 2 Deus for another try-out according to the INGO standard, as a follow-up of the last test.
The objective was to record what effect setting the individual of parameters in the menu have on depthperformance.
Testpiece was (again) the 2 RM-piece (1939 Paul v. Hindenburg) and as my base setting I chose my personal program "FOREST" comprising of the following parameters:

- Disk 0
- 4 Tones, but effectively 3 Tones. T1&2 200Hz., T3 317Hz., T4 791Hz. Threshold T2/3 22, T3/4 80.
- Sens 95, Power 3
- 12 Khz.
- Reactivity 0
- Audio Response 2
- Silencer 1
- G.B Manual 80, following the measurement by the DEUS.

Test:

Using the above mentioned values, the 2RM piece was placed in the ground so that it could just be detected. This was at 23 cm ( the ground was bonedry and the coil not fully charged)
Now every individual parameter was changed and the resulting depthperformance recorded. You should read the results as follows: on the left the setting, on the right the performance in cm's
With depthperformance I mean: a usable signal you would dig.

We started of with the Sensivity.

Sensitivity:

80 / 18cm
85 / 20cm
90 / 21cm
95 / 23cm
98 / 23cm

Frequency:

4 Khz / 23cm
8 Khz / 22,5cm
12 Khz / 23cm
18 Khz / 22cm


Now instead of the big 2RM piece, we tried a silver Hohlpfennig weighing 0,12gr, because frequency should have a noticable effect on the small finds capability of a detector.

4 Khz / 7cm
12 Khz / 12cm
18 Khz / 12,5cm

After which we proceeded again with the 2RM piece and with Recoveryspeed.

Recovery:

0 / 23cm
1 / 23cm
2 / 23,5cm
3 / 22cm
4 / 20cm
5 / 19cm

Audio Response:

0 /23cm
1 / 23cm
2 / 23cm
3 / 23cm
4 / 23cm
5 / 24,5cm

Discrimination:

0 / 23cm
1 / 20cm
2 / 19,5cm
3 / 17,5cm
4 / 17,5cm
10 / 16,5cm
20 / 16,5cm
40 / 16,5cm
60 / 16,5cm

Ground (Deus itself measured a value of 7Cool:

77 / 25cm (but it was totally impossible to detect at 77, due to an incredible amount of false signals)
78 / 24cm
80 / 23cm
85 / 22,5cm
90 / 22cm

Unfortunately I totally forgot about the Silencer settings, but I will test this soon.
I couldn't change the Powersetting, despite the 12 kHz I couldn't change it in the Expertmode.
Obviously the Powersetting is coupled not only with the 4 kHz, but als with some other parameter.
I haven't found out which other setting is blocking the Power parameter in the Expertmode.
May be another Deus user can help me out.

Edited: 30.05.2011:

PS: - just tested the effects of Silencer- and Powersettings

With a freshly charged coil I can now detect the 2RM piece at 26 cm - so it pays off to have a fully charged coil - yesterday with Audioresponse at 5
in program FOREST I could only detect it at 24,5cm.

Power:

I tried all POWER settings more than once, but I can't, for the life of me, find any difference in depthperformance!
This surprises me greatly, I have taken my time with this test - the difference is truly insignificant.
I will use setting "1" in the future to save on batterylife and ask myself: why is it made adjustable at all?

Silencer:

The Silencer setting also doesn't have any noticeable effect on depthperformance - whether set in -1 or 4, performance is the same.
Setting 4 resulted in a less crisp signal and is therefore better not used.
Interesting would be to know if the Silencer has any effect on Recoveryspeed

You're giving all the secrets away. lol

Let's just say, that i am a little tired of hearing that the Deus lacks depth, when it is all about the right settings.:|

Now you know, what makes the Deus gain more depth, so start making some new programs to try out.

 

[woodchiphustler]

In your wording after the first two tones are set how can you set multiple thresholds? Different terminology for threshold then I'm used to.. Sounds to me like your setting Discrimination breaks? Thanks

In the Deus manual it is called threshold, but you can call it discrimination break if you like. Using the 4 tone discrimination thresholds, you can make all metal mode with added zero disc depth benefit with multiple tones and id numbers, very clever.

Thanks for the info finder....Im assuming that with these settings, iron vol is unusable, due to disc set to "0" ?

 

[Larry (IL)]

Now that makes a lot of sense because that is what we do with the V3i, accept all VDI (all metal) and assign 0 Hz tone to what we do not want to hear. Now if XP could make tone 1, 0 Hz instead of 200.............. I would think that would be an easy software upgrade. I will give the no discrimination a try on the Deus and see if I can tolerate the iron.

 

[Deusdigger]

Could you post your forest program parameters please?

 

[Finder82]

Thanks for the info finder....Im assuming that with these settings, iron vol is unusable, due to disc set to "0" ?

As the text says, the iron vol is unusable with the disc set in 0. If you want to hear the iron vol, you could also set the disc at 3.3 as an example to disc out only the smaller iron and set the other tones thresholds as you like, using low disc setting will also increase the detection depth over the factory preset.

This is not my text, so the Forest program is not my creation, but these are the parameters:

Thanks Finder82, did you check the ground mineralization, if so what was it?

Well i have no idea, what the Austrian soil is like.

The iron volume control is simply a volume control for the first tone, which also doubles as the disc. Set the disc at zero and the iron volume control becomes unusable. I'd rather see XP replace it with a volume control that could be used separately with each tone. That way, you could set the disc at zero, set your second tone to cover the iron range and still be able to control the volume of the iron.

 

[Hornetsnesttom]

What threshold number should I put for Tone 1?

 

[CO_T\Huntr]

Goes to show the soil conditions will dictate depth for the most part.....
or so it appears to me!

 

[Hornetsnesttom]

Hey Guys,
Anyone know what threshold setting for Tone one based on the above Forrest program. Tones 2/3 and 3/4 covered. Thanks.
Tom

 

[Hornetsnesttom]

What threshold number should I put for Tone 1?

 

[1afox]

Set the first tone low. it's personal preference. Anywhere between 100 and 200 works for me. This will be your "iron tone". It is tied to your level of discrimination. If you raise the discriminate level the tone cutoff point will raise with it. The iron volume is tied to this. If you raise iron volume you will here this tone when you go over iron. You can lower iron volume and you won't hear it at all. I like to hear a little iron as it helps me ID targets better.

Thanks Brother.
